To all whom'it may concern: 4

Be 'itknown that I, WILLIAM HENRY the United States, residing at Caledonia, in the county of Livingston and State of New York, have invented a new'and useful Bunching' Device for Harvesters, of which the following is a specification. a

v This invention relates to harvesters of that class employed for harvesting crops of beans, peas, or the'like, and has for its rincipal'ob- 'ect to providea novel form of buncher and uncher operating means, whereby the vines may be gathered together in spaced bunches or piles after the cutting operation.

A further object of the invention is to yide a bunching rake in which the rake head is p votally mounted, so as. to be free to turn on its axis to clear a bunch of vines which have been gathered together. 7

With these and other objects in view, as w ll more fully hereinafter a pear, the invention consists in certain nove features of construction and arrangement of parts, herema'fter fully described, illustrated in the accompanying j drawings, and particularly pointed out in the appended claims, it being understood that'various changes in the form,

pr.o portions, size and minor details of the structure may be'made without departing "from the spirit or sacrificing any of the adthe rake head 12, the latter carrying curved 'vanta es 0 is a perspective view 0 the invention.

Similar numerals of reference are employed to indicate corresponding arts throughout the several figures of the d rawings.

The harvesting machine proper may be of the ordinary construction, porting wheels A, an arched axle B, a tongue and cutters D.

Secured rigidly to the frame and projecting rearward therefrom, is a pair of horizontally disposed bars 10, the rear ends of which are provided with journal boxes 11 for the reception of the similar end portions of tines 13 ofany ordinary construction for engaging and gathering the vines into the form of abunch. This rake head is adap e to turn onits axis in order to clear a gat red pro- Fig.

and includes supbunch, and this operatlon is *usually'accomplished once during each com iete rotation of the supporting wheels A, a ter-Whiehtlie fork is again lowered into contact with the ground.

To the forward ortion of the frame is pivoted the front end of a lever 15 that extends rearward and rests upon alug or block 16 that projects from the end of the rake head 10, and near the end of the rake head is secured a crank arm 17 that is eonneetedto the rear end of the lever by a link 18. The lever 15 is arranged close to the inner face of one of the wheels A and secured to said lever is a hanger 20 carrying an anti-friction roller. 21 that is arranged to-be engaged by a cam 22 on the wheel A, and at each rotation of the wheel, this cam will en age the antifriction roller and will swing t e lever 15 upward. This'movement is transmitted from the rear end of the lever to the crank arm 17 through the medium of the link 18, and the rake head is turned on its axis for the urpose of moving the tines upward out 0' engagement with a gathered bunch of vines. As the cam 22 movesfrom enga ement with the anti-frictionroller 21, the ever 15 descends by gravity until its rear end comes into contact with the stop block 16. block limits the downward movement of the lever, and at the same timelimits the descent of the tines13, so that the latter will not swing too far forward, nor come too close into contact with the ground. a

The bracket or hanger 20 is provided with a vertical opening 23 for the passage of a spindle 25 having at its upper end a handled crank 26. At the'lower end of the spindle is an outwardly extending arm 27 on which.

the roller 21 is journaled, so that by turning the crank through an arc of the roller may be moved to a position out of the path of movement of the cam and the buncher will not be operated.
